Neurofascin ( NF ), a cell adhesion molecule expressed in both the central nervous system ( CNS ) and the peripheral nervous system ( PNS ), plays important roles in developing and maintaining neural structures. There are several subtypes of NF resulting from post‐translational modifications: NF 155, 166, 180 and 186. Among them, NF 155 and NF 186 are expressed in the mature CNS / PNS . NF 155 is present on the oligodendroglial cell surface in the CNS and on the Schwann cell surface in the PNS at paranodes, where it tightly connects with contactin and caspr on the axonal surface of the paranode, and acts as a stabilizer of the nodes of Ranvier. NF 186 exists on the axonal surface at the nodes of Ranvier. NF 186 is associated with voltage‐gated Na channels (Nav), whereas both NF 186 and Nav are anchored by ankyrin G. NF 186 contributes to the clustering of Nav at the node. Combined central and peripheral demyelination ( CCPD ) is an inflammatory demyelinating disorder affecting both the CNS and PNS tissues. Distinct mechanisms including multiple sclerosis and chronic inflammatory demyelinating polyradiculoneuropathy have been hypothesized to play a role in this condition on the basis of distinctive clinical and laboratory findings. We detected anti‐ NF 155 antibody by cell‐based assay, enzyme‐linked immunosorbent assay, and western blot in both the sera and cerebrospinal fluids of CCPD patients at high frequencies, but did not detect it in patients with other neurological disease or healthy controls. Herein, basic aspects and the clinical significance of NF as indispensable regulators and autoimmune target molecules are summarized.
